Record time marks.

<P><STRONG>Functional Details</STRONG>
<P>
<TT><STRONG>DXMarkTime</STRONG></TT> records a "global" time mark
relevant to the system as a whole.
<P>
<TT><STRONG>DXMarkTimeLocal</STRONG></TT> records a "local" event
relevant to one processor (e.g., during a parallel
section).
This routine is called by the executive at the beginning and end of
each module, at the beginning and end of each task or parallel
section, and by some system modules.
<P>
Both routines store the current time (from <TT><STRONG>DXGetTime</STRONG></TT>)
and a copy of <TT><STRONG>string</STRONG></TT> in a
processor local list.
The copied version of <TT><STRONG>string</STRONG></TT> will be truncated if
longer than 16 characters.
The number of time marks stored since the last call to
<TT><STRONG>DXPrintTimes</STRONG></TT> is limited to
2000 events.
<P>
<P><STRONG>Return Value</STRONG>
<P>
None.
